Abstract
SISTEMA Y PROCEDIMIENTO QUE REDUCE O ELIMINA EL COSTO ADICIONAL ASOCIADO A LA PROVISIÓN DE CAPACIDAD EXTRA DE UN TAMBOR DE VAPOR Y/O UNA BOMBA DE AGUA PARA UNA CALDERA INDEPENDIENTEMENTE IMPULSADA, EN EL EVENTO DE UNA CONDICIÓN DE PLANTA NEGRA EN UNA DISPOSICIÓN DE CALDERA DE LECHO FLUIDIZADO CIRCULATORIO, EN DONDE<br /> DICHA DISPOSICIÓN TIENE UN SISTEMA SEPARADOR DE SÓLIDOS Y UN CIRCUITO DE VAPOR/AGUA, QUE HACE CIRCULAR VAPOR Y AGUA EN LA DISPOSICIÓN DE CALDERA, Y EN DONDE DICHO SISTEMA COMPRENDE ADEMÁS MEDIOS PARA TRANSPORTAR VAPOR DESDE EL CIRCUITO DE VAPOR/AGUA; Y MEDIOS PARA INYECTAR EL VAPOR TRANSPORTADO DENTRO DE UN HORNO, Y ASÍ ENFRÍAR AL SISTEMA SEPARADOR DE SÓLIDOS Y REDUCIR LA PRESIÓN EN EL CIRCUITO VAPOR/ AGUA, ADICIONALMENTE, SE<br /> REIVINDICA UNA DISPOSICIÓN DE CALDERA DE LECHO FLUIDIZADO, QUE TIENE UN CIRCUITO DE VAPOR/AGUA, UN TAMBOR DE VAPOR, UN HORNO DE LECHO FLUIDIZADO CIRCULATORIO CON UN SISTEMA SEPARADOR DE SÓLIDOS Y UN SISTEMA DE REDUCCIÓN SELECTIVA NO CATALÍTICO, QUE EMPLEA VAPOR COMO UN VEHÍCULO DE FLUJO DE GAS PARA UN AGENTE REDUCTOR DE NOX Y UN SISTEMA DE DESCARGA DE VAPOR. EL PROCEDIMIENTO REIVINDICADO, COMPRENDE LOS PASOS PROVEER UNA FUENTE DE VAPOR Y DESCARGAR EL VAPOR DENTRO DEL RECORRIDO DEL FLUJO DE GAS DURANTE UNA CONDICIÓN DE PLANTA NEGRA, PARA ENFRIAR ASÍ A LOS COMPONENTES CALIENTES DE LA CALDERA.
